RPM23BD Equivalent & Substitute Parts

Part Overview

The RPM23BD is a Harmony series general purpose relay manufactured by Schneider Electric. This socketable, plug-in relay features a DPDT (2 Form C) contact configuration with a 24VDC coil and 15A contact rating. The RPM23BD is an active product with full regulatory compliance including CSA, EAC, and UL approvals. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity for applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RPM23BD are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• Coil voltage: 24VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 15 A
• Switching voltage: 250VAC, 28VDC - Max
• Mounting type: Socketable
• Termination style: Plug In
• Coil type: Non Latching
• Operating temperature range: -40°C ~ 55°C
• Contact material: Silver Nickel (AgNi)
• Coil resistance: 640 Ohms
• Must operate voltage: 19.2 VDC
• Must release voltage: 2.4 VDC
• Operate time: 20 ms
• Release time: 20 ms
• Coil current: 37.5 mA
• Approval agencies: CSA, EAC, UL
• RoHS compliance: ROHS3 Compliant

The RPM21BD meets all these criteria and is classified as a parametric equivalent to the RPM23BD within the Harmony series.

Parameter Comparison

Engineering Selection Recommendations

Both the RPM23BD and RPM21BD are active products manufactured by Schneider Electric within the Harmony series. Both parts carry identical regulatory certifications from CSA, EAC, and UL, confirming compliance with applicable standards. Both parts are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial applications.

The RPM21BD functions as a direct parametric equivalent to the RPM23BD. All electrical characteristics, mechanical specifications, and performance parameters are identical. Both parts are socketable, plug-in relays with identical coil specifications, contact ratings, and switching capabilities. The parts are interchangeable in applications requiring a 24VDC coil, DPDT contact configuration, and 15A switching capacity.

Selection between these parts may be based on inventory availability, lead time, or procurement preference, as both parts meet identical technical requirements for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the RPM21BD be used as a direct replacement for the RPM23BD?

A: Yes. The RPM21BD is a parametric equivalent to the RPM23BD. All electrical specifications, mechanical dimensions, contact ratings, coil characteristics, and performance parameters are identical. Both parts are socketable, plug-in relays within the Harmony series with 24VDC coils and DPDT contact configurations rated for 15A switching.

Q: Are there any differences in regulatory compliance between the RPM23BD and RPM21BD?

A: No. Both parts carry identical certifications from CSA, EAC, and UL. Both parts are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent across both parts.

Q: What are the key parameters that define substitution eligibility for this relay?

A: Substitution eligibility is determined by matching the following parameters: coil voltage (24VDC), contact form (DPDT), contact rating (15A), switching voltage (250VAC, 28VDC - Max), mounting type (socketable), termination style (plug-in), coil type (non-latching), operating temperature range (-40°C ~ 55°C), contact material (Silver Nickel), coil resistance (640 Ohms), and all timing specifications (operate and release times of 20 ms each).

Q: Can these relays be used in applications requiring different coil voltages?

A: No. Both the RPM23BD and RPM21BD are designed exclusively for 24VDC coil operation. They are not suitable for applications requiring different coil voltages.

Q: What is the maximum switching capacity of these relays?

A: The RPM23BD is rated for maximum switching loads of 3750VA at 250VAC or 420W at 28VDC. The RPM21BD specifications do not include maximum load switching data in the provided parameters.

Q: Are these relays suitable for high-temperature applications?

A: Both relays operate within the temperature range of -40°C to 55°C. Applications requiring operation outside this range require alternative relay designs.

Q: What is the socketable mounting configuration?

A: Both relays feature socketable, plug-in termination. This mounting type allows the relay to be inserted into a compatible socket base, enabling tool-free installation and removal without soldering or permanent connections.
